With DeltaV Simulate, you can simulate the execution of operator interface and selected control modules defined for your plant. You can use this capability for control logic checkout. Also, using the Control and I/O block simulation capability of the DeltaV system and fieldbus, field measurement values and status can be manually supplied to the simulation or provided by blocks used to simulate the process.
The full range of OPC features in the DeltaV system are available with DeltaV Simulate. You can use this capability for the development and testing of OPC interfaces to the DeltaV system. Also, before your plant is even constructed, you can use OPC-compliant process simulation packages with DeltaV Simulate for process and control design checkout one controller at a time.
